Would u consider this a date?

Would u consider this a date?Today, was the last day of school. One of my friends in class asked me out to go eat with him after class. I said of course. When we ate at the restaurant, he paid for my food, without saying anything. I was surprised since I always pay for my own food when going out with friends. My question is did he considered it a data, is that why he paid for my food. I also noticed that while eating, he was looking at my face, and then looking down to my waist and then back to my eyes. Later this day, he facebook friend requested me. Would u consider this a date?
